Queens solution, step by step

Each LinkedIn Queens step places one queen and closes its row, its column, its region and the squares touching it.

1. Step 1: The Blue region sits entirely in row 2, so no other queen can go in row 2. The Green region sits entirely in row 3, so no other queen can go in row 3. The Orange region sits entirely in row 4, so no other queen can go in row 4. The Beige region sits entirely in row 7, so no other queen can go in row 7. The Yellow region sits entirely in row 6, so no other queen can go in row 6. The Gray region sits entirely in row 5, so no other queen can go in row 5. The Red region sits entirely in row 8, so no other queen can go in row 8. Column 8 has only one open square left, so its queen goes in row 1 (Purple region) (R1C8).
2. Step 2: Column 1 has only one open square left, so its queen goes in row 8 (Red region) (R8C1).
3. Step 3: A queen in row 2, column 6 would leave the Green region with no open square, so that square is out. The Blue region has only one open square left, so its queen goes in row 2, column 5 (R2C5).
4. Step 4: The Green region has only one open square left, so its queen goes in row 3, column 7 (R3C7).
5. Step 5: The Gray region has only one open square left, so its queen goes in row 5, column 6 (R5C6).
6. Step 6: A queen in row 6, column 3 would leave the Beige region with no open square, so that square is out. A queen in row 6, column 4 would leave the Beige region with no open square, so that square is out. The Yellow region has only one open square left, so its queen goes in row 6, column 2 (R6C2).
7. Step 7: The Orange region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
8. Step 8: The Beige region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
